Syntax highlighting incorrect for type literals

[rcchen]

protected _normalizeDatasets<A, B>(fromX: boolean): {a: A; b: B}[] {
  return Stacked.prototype._normalizeDatasets.call(this, fromX);
}

The typed object literal for the return typing "{a: A; b: B}" wrecks syntax highlighting for the rest of the page. I have tried putting a semicolon after the B as well and the syntax highlighting is still incorrect. Is this an issue with my syntax, or is there a bug with the plugin?
